Abstract

This thesis mainly focuses on the analysis of design and signal integrity issues involved in highspeed electrical link components including differential-pairs, multichannel connectors, and cables. The main purpose of this research is to work through high-speed component and system signal integrity analysis, address the key problems confronted in each design-andanalysis stage, and further develop validated express tools. FEM (Finite element method) simulators were used to analyze field distributions, examine Sparameter results at electrical ports, and investigate parasitic effects for electrical link components with arbitrary 3D geometries. Design optimization was reached with the design parameter sweeps. A faster simulation was developed using distributed-lumped subcomponent transformation. Signal integrity diagnoses were enabled via integration of 3D modeler and 2D schematics or layout, S-parameter analysis, channel simulation with TX/RX equalization, preemphasis, encoding, and crosstalk setup. Test-fixture de-embedding and embedding were used to improve the correlation between simulation and measurement on the device-under-test (DUT) model. With effort on investigating design and validation on components and system, the signal integrity workflow on high-speed electrical links was better understood and will be further utilized to improve the performance of millimeter-wave systems.
